The BeautyFile app helps women take control of their ‘beauty routines’
As increasing numbers of consumers (mainly women) turn to cosmetic treatments such as Botox and dermal fillers to help them look their very best it is often difficult for them to remember exactly what they have had done, when, where, and by whom.  

It is however essential they do ‒ to keep them safe and ensure they get the best possible results from their treatments.

BeautyFile enables users to quickly and easily create and store records of all their treatments (including salon contacts, costs and before-and-after photos) in one safe place.
